Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail and completely with reference to the following specific embodiments of the present application and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

In some embodiments of the present application, a solution is provided, where the solution includes a communication system composed of a data sending end and a data receiving end. Technical solutions provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

Fig. 1a is a schematic structural diagram of a communication system according to an exemplary embodiment of the present application, and as shown in fig. 1a, the communication system 100 includes: a data transmitting end 10a and a data receiving end 10 b.

In the communication system 100, the data transmitting end 10a refers to a device capable of receiving communication data to be transmitted and transmitting the received communication data according to a set communication protocol.

Generally, the data transmitting end 10a has an input device for receiving data input by a user. For example, in some embodiments, the data transmitting end 10a may include an electronic touch screen that may receive input signals from a user to obtain data input by the user. For example, the data transmitting end 10a may be provided with a physical key through which the user can input data. For another example, the data sending end 10a may have a voice input device, which can detect and receive the voice content sent by the user, as the data input by the user, and will not be described in detail.

Under different application scenarios, the data sender 10a may have different implementation forms. For example, in some scenarios, the data transmitting end 10a may be implemented as a mobile phone, a tablet computer, a notebook computer, an intelligent watch, an intelligent bracelet, an interphone, and other portable devices on the user side; in other scenarios, the data transmitting end 10a may be implemented as a stationary device such as a desktop computer, a fixed telephone, a smart speaker, etc., but the embodiment includes but is not limited to this.

In the communication system 100, the data receiving end 10b refers to a device capable of receiving communication data according to a set communication protocol. The data receiving end 10b also has, in general, data output means for outputting the received communication data to the user. For example, in some embodiments, data receiving end 10b may include a display screen that may present the received communication data. For another example, the data receiving end 10b may include an audio component, and the audio component may play the received communication data, which is not described in detail. In some scenarios, the data receiving end 10b may also be implemented as any one of the above-mentioned portable devices, or any one of the above-mentioned fixed devices, and the embodiment is not limited thereto.

In some scenarios, the data sending end 10a and the data receiving end 10b may have the same implementation form, for example, both the data sending end 10a and the data receiving end 10b may be implemented as a mobile phone on the user side; in other scenes, the data sending end 10a and the data receiving end 10b may be implemented in different forms, for example, the data sending end 10a may be implemented as an intelligent speaker placed in the home of the user, and the data receiving end 10b may be implemented as an intelligent watch worn by the user.

It should be understood that data transmission and data reception are relative actions, and therefore, the data transmitting end 10a does not refer to a certain device in the communication system, but refers to a device performing a data transmission action in the communication system; accordingly, the data receiving end 10b refers to an apparatus that performs a data receiving action in the communication system. For example, in a communication system formed by a smart speaker and a smart watch, when the smart speaker transmits data to the smart watch, the smart speaker may be referred to as a data transmitting end, and the smart watch may be referred to as a data receiving end; when the smart watch sends data to the smart sound box, the smart watch can be called a data sending end, and the smart sound box can be called a data receiving end.

In the communication system 100 provided in this embodiment, in some typical scenarios, the data sending end 10a is mainly configured to: acquiring the network quality of the data sending end 10 a; when the network quality of the data sending end 10a does not meet the data transmission condition, caching communication data to be sent to the data receiving end 10b to obtain cached data; when the network quality of the data transmitting end 10a itself meets the data transmission condition, the real-time communication data is transmitted to the data receiving end 10b by using the first transmission channel, and the cache data is transmitted to the data receiving end 10b by using the second transmission channel.

Alternatively, in other typical scenarios, the data sender 10a is mainly configured to: acquiring the network quality of the data receiving end 10 b; when the network quality of the data receiving terminal 10b does not satisfy the data transmission condition, caching communication data to be sent to the data receiving terminal 10b to obtain cached data; when the network quality of the data receiving terminal 10b satisfies the data transmission condition, the real-time communication data is transmitted to the data receiving terminal 10b by using the first transmission channel, and the cache data is transmitted to the data receiving terminal 10b by using the second transmission channel.

The second transmission channel is independent of the first transmission channel, so that the buffer data transmitted in the second transmission channel is prevented from influencing the real-time communication data transmitted in the first transmission channel.

The communication data to be sent to the data receiving end 10b may be data input by the user to the data sending end 10a, or may also be data transmitted by other devices or other processes on the data sending end 10a, which is not limited in this embodiment.

The network quality of the data sending end 10a is used to analyze whether the network performance of the data sending end 10a can ensure that the data can be sent out. The network quality of the data receiving end 10b is used to analyze whether the network performance of the data receiving end 10b can ensure that the data receiving end 10b receives the communication data more completely.

Wherein the network quality may be evaluated using one or more different evaluation factors. In some embodiments, the evaluation factors for evaluating network quality may include, but are not limited to, one or more of a network on-off condition, a network delay condition, network stability, and a network packet loss rate.

Wherein, an evaluation factor can correspond to an evaluation index. For example, the evaluation indexes corresponding to the network on-off condition are as follows: the network is not interrupted; the evaluation indexes corresponding to the network delay condition are as follows: the network delay is less than the set time length threshold. The evaluation indexes corresponding to the network packet loss rate are as follows: and the network packet loss rate is less than the set packet loss rate threshold.

In some exemplary embodiments, a plurality of evaluation factors may be used to evaluate the network quality so as to comprehensively analyze the network performance of the data transmitting end 10a or the data receiving end 10 b. When any one of the plurality of evaluation factors does not satisfy its corresponding evaluation index, it can be considered that the network quality does not satisfy the data transmission condition. When various factors all meet the corresponding evaluation indexes, the network quality can be considered to meet the data transmission condition. The following description will be made with reference to specific examples.

For example, when the evaluation factors corresponding to the network quality are the network on-off condition and the network packet loss rate, if the network of the data receiving end 10b is not interrupted, but the network delay is greater than the set time threshold, it is determined that the network quality of the data receiving end 10b does not satisfy the data transmission condition, and at this time, the communication data to be sent to the data receiving end 10b may be cached. If the network of the data receiving terminal 10b is not interrupted and the network delay is less than the set time threshold, the network quality of the data receiving terminal 10b may be considered to meet the data transmission condition, and at this time, the real-time communication data may be sent to the data receiving terminal 10b by using the first transmission channel, and the cache data may be sent to the data receiving terminal 10b by using the second transmission channel, which is not described again.

In the communication system 100, in order to implement the above-mentioned data interaction process between the data sending end 10a and the data receiving end 10b, the data sending end 10a and the data receiving end 10b may establish a communication connection, and a specific communication connection manner may depend on an actual application scenario.

In some exemplary embodiments, the data transmitting end 10a and the data receiving end 10b may communicate with each other by wireless communication in a wired communication manner. The WIreless communication mode includes short-distance communication modes such as bluetooth, ZigBee, infrared, WiFi (WIreless-Fidelity), long-distance WIreless communication modes such as LORA, and WIreless communication mode based on a mobile network. When the mobile network is connected through communication, the network format of the mobile network may be any one of 2G (gsm), 2.5G (gprs), 3G (WCDMA, TD-SCDMA, CDMA2000, UTMS), 4G (LTE), 4G + (LTE +), 5G, WiMax, and the like.

In this embodiment, when the network quality of the data transmitting end or the data receiving end does not satisfy the data transmission condition, the communication data to be transmitted to the data receiving end can be cached to obtain cached data; when the network quality of the data receiving end meets the data transmission condition, the real-time communication data can be sent to the data receiving end by adopting the first transmission channel, and the cache data can be sent to the data receiving end by adopting the second transmission channel. In the embodiment, the real-time communication data and the cache data are transmitted by adopting two different transmission channels, and further, the communication data which is not successfully transmitted when the network environment is unstable can be transmitted on the premise of not influencing the transmission of the real-time communication data, so that the risk of communication data loss caused by the instability of the network environment is effectively reduced.

In the above and following examples of the present application, the mutually independent feature between the first transmission channel and the second transmission channel means that the two transmission channels for transmitting the real-time communication data and the buffer data are mutually independent in service logic. The embodiment of the present application can adopt various implementation manners to implement the first transmission channel and the second transmission channel that are independent of each other, and an exemplary description will be given below.

In some exemplary embodiments, the data sender 10a and the data receiver 10b may establish a communication connection through a plurality of pairs of sockets. Wherein each pair of sockets corresponds to one transmission channel. For example, the data transmitting end 10a and the data receiving end 10b may establish a first transmission channel through a first pair of sockets, and establish a second transmission channel through a second pair of sockets.

The socket is a network development interface provided by a transport protocol used by a transport layer, and two programs on the network can exchange data through a communication connection established by the socket.

For example, when the data transmitting end 10a and the data receiving end 10b communicate based on UDP (User Datagram Protocol), the first pair of sockets and the second pair of sockets may be provided by UDP, and based on this, two UDP transmission channels may be obtained.

For another example, when the data transmitting end 10a and the data receiving end 10b communicate based on TCP (Transmission Control Protocol), the first pair of sockets and the second pair of sockets may be provided by TCP, and based on this, two TCP Transmission channels may be obtained.

For another example, when the data transmitting end 10a and the data receiving end 10b communicate based on UDP and TCP, the first pair of sockets may be provided by UDP, and the second pair of sockets may be provided by TCP; alternatively, the first pair of sockets may be provided by TCP and the second pair of sockets may be provided by UDP, based on which one UDP transport channel and one TCP transport channel are available.

In other exemplary embodiments, the data transmitting end 10a and the data receiving end 10b may establish a communication connection using a pair of sockets. Before transmitting the real-time communication data and the buffer data, the data transmitting end 10a may use different headers to respectively encapsulate the real-time communication data and the buffer data, so that the data packets with different headers are independently transmitted on one data channel. After receiving the data packet, the data receiving end 10b may allocate the data packet to a corresponding process according to a difference between the headers of the data packet.

For example, the header of the real-time communication data is H1, and the header of the buffered data is H2. If the real-time communication data is in audio format and the buffer data is in text format, the data receiving end 10b may allocate the received packet with header H1 to the audio playing process and allocate the packet with header H2 to the text displaying process. It should be understood that, in this embodiment, after abstracting the transmission process of the data packet with the header H1 and the data packet with the header H2, the data packet with the header H1 and the data packet with the header H2 can be considered to be transmitted by using two independent transmission channels. The data packet with the header H1 may correspond to the first transmission channel, and the data packet with the header H2 may correspond to the second transmission channel, which is not described again.

The above embodiment describes an implementation that the data sending end 10a in the communication system 100 can send the buffered data to the data receiving end 10b by using the second transmission channel independent from the first transmission channel when the network quality of the data receiving end 10b satisfies the data transmission condition. The sending of the buffered data to the data receiving end 10b by using the second transmission channel may be implemented by different embodiments, and the following exemplary descriptions are provided:

in a typicalEmbodiment mode S1The data sending end 10a may send a prompt message for checking the lost data to the data receiving end 10b by using the second data transmission channel; further, the data receiving end 10b may send a request for checking the missing data according to the prompt message at the direction of the user. Next, the data sending end 10a may respond to the data checking request sent by the data receiving end 10b according to the prompt message, and send the cached data to the data receiving end 10b by using the second data transmission channel.

For example, the data sender 10a may push a text message to the data receiver 10b, where the text message includes: "do you have lost communication data, do you query? When the data receiving end 10b receives the text message, it may present the text message and detect the user's operation on the text message. In some exemplary embodiments, a user may click on a text message presented by data receiving end 10b to issue a request to view a missing text message. The data receiving end 10b may send a data viewing request to the data sending end 10a according to a click operation of the user on the text message.

Further optionally, the data receiving end 10b may display at least one selection control, such as a query time selection control, a query mode selection control, a data format selection control, and the like, which includes but is not limited to this embodiment. The query time selection control can provide a time setting entrance for a user to set when to check the lost data; for example, the user may set to view the missing data immediately, five minutes later, or half an hour later. The query mode selection control can provide a query mode setting entry for a user to set that the lost data is checked by adopting an instant message mode, or the lost data is checked by adopting an e-mail mode, or the lost data is checked by adopting other user-defined modes. The data format selection control is used for providing a data format setting inlet for a user, and the user can select whether to convert the format of the lost data or not through the data format selection control; for example, the user may select to view the missing data in the original format of the audio format, or select to view the missing data in the audio format after converting the missing data in the audio format into the missing data in the text format, and details are not repeated.

In another typeEmbodiment mode S2In the above embodiment, the data sending end 10a may not send the hint message to the data receiving end 10b, but directly send the cache data to the data receiving end 10b by using the second transmission channel in combination with the network quality of the data sending end 10a or the network quality of the data receiving end 10 b. As will be described in detail below.

Optionally, in an embodiment, the data sending end 10a may determine the remaining available bandwidth in the uplink bandwidth of itself according to the network quality of itself. The remaining available bandwidth in the uplink bandwidth refers to a current bandwidth remaining amount in the uplink bandwidth of the data sending end 10a, except for a bandwidth occupied by the first transmission channel for transmitting the real-time communication data and a bandwidth occupied by other network uploading behaviors of the data sending end 10 a.

If the remaining available bandwidth in the uplink bandwidth of the data sending end 10a is greater than or equal to the set bandwidth threshold, the data sending end 10a may directly send the cached data in the original format to the data receiving end 10 b. In this embodiment, the data sender 10a may send the buffered data to the data sender 10b in a timely manner, and the integrity and authenticity of the buffered data is preserved.

If the remaining available bandwidth in the uplink bandwidth of the data sending end 10a is smaller than the set bandwidth threshold, the data sending end 10a may compress the cache data, and send the compressed cache data to the data receiving end 10b by using the second transmission channel. The compression processing of the cache data means that the data volume of the cache data is reduced on the premise that useful information in the cache data is not lost. Based on this embodiment, the data sending end 10a can effectively reduce the bandwidth cost required for transmitting the buffered data, and does not affect the transmission of the real-time communication data on the first transmission channel.

Optionally, in another embodiment, the data sending end 10a may determine the remaining available bandwidth in the downlink bandwidth of the data receiving end 10b according to the network quality of the data receiving end 10 b; the remaining available bandwidth in the downlink bandwidth refers to a current bandwidth remaining amount in the downlink bandwidth of the data receiving end 10b, except for a bandwidth occupied by the first transmission channel for transmitting the real-time communication data and a bandwidth occupied by other network downloading behaviors of the data receiving end 10 b. If the remaining available bandwidth in the downlink bandwidth of the data receiving end 10b is greater than or equal to the set bandwidth threshold, the data sending end 10a may directly send the cached data in the original format to the data receiving end 10 b. In this embodiment, the data sender 10a can send the buffered data to the data receiver 10b in a timely manner, and the integrity and authenticity of the buffered data is preserved.

If the remaining available bandwidth in the downlink bandwidth of the data receiving end 10b is smaller than the set bandwidth threshold, the data sending end 10a may compress the cache data, and send the compressed cache data to the data receiving end 10b by using the second transmission channel. The compression processing of the cache data means that the data volume of the cache data is reduced on the premise that useful information in the cache data is not lost. Based on this embodiment, the data sending end 10a can effectively reduce the bandwidth cost required for transmitting the buffered data, and does not affect the transmission of the real-time communication data on the first transmission channel.

Optionally, in this embodiment, if the original format of the cached data is different, the manner of compressing the cached data is also different. As will be exemplified below.

In an exemplary embodiment, if the cache data contains audio data, the data sending end 10a may perform voice recognition on the audio data, and obtain text data corresponding to the audio data according to a result of the voice recognition. Therefore, the audio data with large data volume can be converted into the text data with small data volume, and the data volume of the cache data is greatly compressed.

Further, semantic recognition can be performed on the text data obtained by the voice recognition conversion, and a content summary can be extracted from the text data based on the result of the semantic recognition. Therefore, the data volume of the cache data can be further compressed, and the key data lost by the user can be pushed to the user in time on the premise of not influencing real-time data transmission.

In other exemplary embodiments, if the buffered data contains image data such as video and pictures, the data sending end 10a may reduce the resolution of the image data to compress the data size of the image data. Alternatively, in such an embodiment, the data transmitting end 10a may provide the data receiving end 10b with a portal for viewing the original image data, and may transmit the original image data to the data receiving end 10b according to a request for viewing the original image data by the data receiving end 10 b. In this embodiment, the data receiving end 10b can quickly display the key information in the lost data to the user based on the received image data with lower resolution in cooperation with the data sending end 10a, and can display the original image data to the user according to the user's requirement, and meanwhile, the efficiency of receiving real-time communication data and the efficiency of checking the lost data by the user are both considered, and the user experience is greatly improved.

It is noted thatEmbodiment mode S1Andembodiment mode S2On the basis of the corresponding embodiments, the data transmitting end 10a may further perform the implementation described in the following embodiments to further compress the data size of the cache data, which will be described in detail below.

In some exemplary embodiments, the data sending end 10a may perform an effective data extraction operation on the cached data before sending the cached data to the data receiving end 10b by using the second transmission channel; then, the extracted valid data is transmitted to the data receiving end 10b through the second transmission channel. The valid data is data including information amount or data having a substantial meaning to both communication parties.

Based thereon, optionally, atEmbodiment mode S1In a corresponding embodiment, the data sending end 10a may extract valid data from the cache data after obtaining the cache data; then, in response to the data viewing request sent by the data receiving end 10b, the extracted valid data is sent to the data receiving end 10b through the second data transmission channel.

Optionally, inEmbodiment mode S2In a corresponding embodiment, the data sending end 10a may extract valid data from the cache data after obtaining the cache data; next, when the remaining available bandwidth in the uplink bandwidth of the data sending end 10a is smaller than the set bandwidth threshold or the remaining available bandwidth in the downlink bandwidth of the data receiving end 10b is smaller than the set bandwidth threshold, the extracted valid data is compressed, and the compressed valid data is sent to the data receiving end 10b through the second data transmission channel.

Generally, the types of the cache data are different, and the extraction operation of the valid data is also different.

In some exemplary embodiments, if the buffered data contains audio data, the data sending end 10a may perform silence detection on the audio data to identify silence data in the audio data; then, the data transmitting end 10a may remove the mute data from the audio data, and obtain the valid data in the audio data. The silence detection may be implemented based on the energy, spectrum or waveform of the audio data including the voice signal, which is not described herein.

In other exemplary embodiments, if the buffered data includes image data such as video and picture, the data sending end 10a may perform feature recognition on the image data to identify useless information in the image data, for example, identify a background portion and a noise portion in the image data; next, the data transmitting end 10a may remove unnecessary information from the image data to obtain valid data in the image data.

As shown in fig. 1b, in some example embodiments, two data buffers may be provided at the data sender 10 a: a receive buffer and a transmit buffer. The receiving buffer is used for storing the received communication data to be sent to the data receiving end 10 b. And the sending buffer area is used for storing effective data extracted from the data stored in the receiving buffer area. Based on this, when the network quality of the data receiving end 10b meets the data transmission condition, the data transmitting end 10a can directly read the valid data from the transmission buffer area, and the second transmission channel is adopted to transmit the read valid data to the data receiving end 10b, so that the efficiency is higher.

Based on the effective data identification implementation provided in the foregoing embodiment, on one hand, the data sending end 10a further compresses the data size of the cache data, and reduces the transmission bandwidth occupied by the second transmission channel; on the other hand, the data sending end 10a screens out valid data from the cached data, and the efficiency of quickly capturing key information from the lost data by the user is greatly improved.

It should be noted that, in the communication system 100 provided in each of the above embodiments, the data transmitting end 10a may communicate with one or more data receiving ends 10 b. When there are multiple data receiving terminals 10b, the data sending terminal 10a may execute the communication method described in the foregoing embodiments for each data receiving terminal 10b, and details are not repeated.

The above embodiments provide a communication system 100 composed of a data transmitting end 10a and a data receiving end 10b, and in alternative embodiments, a communication system 300 composed of a data transmitting end 30a, a server 30b and a data receiving end 30c is also provided. The system architecture shown in fig. 2a will be described in detail below.

In this embodiment, data interaction between the data sender 30a and the data receiver 30c can be implemented by the server 30 b. The server 30b may be implemented as a conventional server, a cloud host, a virtual center, or other devices, which is not limited in this embodiment. The server device mainly includes a processor, a hard disk, a memory, a system bus, and the like, and is similar to a general computer architecture, and is not described in detail.

In the communication system 300, the implementation form of the data transmitting end 30a may refer to the description of the above embodiment about the optional implementation form of the data transmitting end 10 a; for the implementation of the data receiving end 30c, reference is made to the description of the optional implementation of the data receiving end 10b in the above embodiments, and details are not repeated here.

The data sending end 30a is configured to: the communication data to be transmitted to the data receiving terminal 30c is transmitted to the server 30 b. The communication data to be sent to the data receiving end 30c may be data input by the user to the data sending end 30a, or may also be data transmitted by other devices or other processes on the data sending end 30a, which is not limited in this embodiment.

A server 30b for: receiving communication data to be sent to a data receiving end 30c, which is sent by a data sending end 30a, and detecting the network quality of the data receiving end 30 c; when the network quality of the data receiving terminal 30c does not satisfy the data transmission condition, buffering the received communication data to be sent to the data receiving terminal 30c to obtain buffered data; when the network quality of the data receiving terminal 30c satisfies the data transmission condition, the received real-time communication data is transmitted to the data receiving terminal 30c using the first transmission channel, and the cache data is transmitted to the data receiving terminal 30c using the second transmission channel.

In addition to the above execution logic, the server 30b may also execute other method logic that can be executed by the data sending end 10a in the communication system 100, which may specifically refer to the description of the foregoing embodiments and is not described herein again.

Alternatively, when the server 30b executes the logic of the method for the data sender 10a to extract valid data from the buffered data, the receiving buffer and the sending buffer arranged at the data sender 10a shown in fig. 1b may be arranged on the server 10b, as shown in fig. 2 b. When the network quality of the data receiving end 30c does not satisfy the data transmission condition, the server 30b may buffer the received communication data transmitted from the data transmitting end 30a in a receiving buffer. Next, the server 30b may extract valid data from the buffer data stored in the receiving buffer, and store the valid data in the sending buffer. Based on this, when determining that the network quality of the data receiving end 30c meets the data transmission condition, the server 30b may directly read the valid data from the sending buffer, and send the read valid data to the data receiving end 30c by using the second transmission channel, which is more efficient.

The communication system provided by the above embodiments can be applied to various application scenarios, and will be described below with reference to specific examples.

In a typical application scenario, as shown in fig. 3, user a and user B make voice over internet calls via respective handsets. The user A is located in an office and holds the mobile phone Ma; the user B is located on a traveling train and holds the mobile phone Mb.

As shown in fig. 4, the mobile Ma detects the network quality of the mobile Mb in real time. Conversely, the mobile phone Mb also detects the network quality of the mobile phone Ma in real time. When the mobile phone Ma receives the voice signal sent by the user a, whether the mobile phone Mb is disconnected or the situation of high network packet loss rate exists can be judged according to the network quality of the mobile phone Mb.

If the train taken by the user B travels in the signal coverage area of the communication base station, the mobile phone Mb should detect that the network of the mobile phone Mb is in a connected state, and the network packet loss rate is low. At this time, the mobile phone Ma may send the voice signal sent by the user a to the mobile phone Mb in real time to convey the call content of the user a to the user B.

If the train taken by the user B enters a tunnel or a cave at this time, the mobile phone Mb should detect that the signal of the mobile phone Mb is weakened or the signal is interrupted, and the network packet loss rate is high. At this time, the mobile phone Ma may buffer the voice signal sent by the user a in the local receiving buffer.

The mobile phone Ma continues to detect the network quality of the mobile phone Mb in real time. Meanwhile, the mobile phone Ma can perform voice recognition and analysis on the voice data cached in the receiving buffer, and judge whether the voice data is valid. If there is invalid voice data, it is discarded. If the valid voice data exists, the valid voice data is migrated to the local sending buffer area.

If the train taken by the user B runs out of the tunnel or the cave after a period of time and returns to the signal coverage area of the communication base station again, the mobile phone Ma detects that the network of the mobile phone Mb is in a connection state, and the network packet loss rate is low. At this time, if the user a is still speaking to the mobile phone Ma, the mobile phone Ma may send the part of the real-time generated voice data to the mobile phone Mb through the transmission channel C1.

Meanwhile, if the local sending buffer of the mobile phone Ma stores data, the mobile phone Ma can send a voice message loss reminder to the mobile phone Mb through the transmission channel C2 to remind the user of the lost voice message, and ask the user to check the lost voice content in a text format or listen back to the lost voice content in an audio format. If the user selects the text format, the voice data in the transmission buffer is recognized as text data and transmitted to the mobile phone Mb for display through the transmission channel C2. If the user selects the audio format, the voice data in the sending buffer area is directly sent to the mobile phone Mb through the transmission channel C2 for the user to play.

Or, if it is detected that the network of the mobile phone Mb is in a connected state, the network packet loss rate is low, and the local sending buffer stores data, the mobile phone Ma further determines the remaining available bandwidth in the downlink bandwidth of the mobile phone Mb, and if the remaining available bandwidth is large, the voice data in the sending buffer is directly sent to the mobile phone Mb through the transmission channel C2 for the user to play. If the remaining available bandwidth is small, the voice data of the transmission buffer is recognized as text data and transmitted to the mobile phone Mb for presentation via the transmission channel C2.

In addition to the communication systems provided by the above embodiments, the embodiments of the present application also provide a communication method, which will be described below with reference to the accompanying drawings.

Further optionally, the method further comprises: valid data is extracted from the cached data. Based on this, in step 607, the second transmission channel may be adopted to transmit the valid data extracted from the buffered data to the data receiving end.

In some exemplary embodiments, one way to extract valid data from the cached data may include: if the cache data contains audio data, performing silence detection on the audio data to identify silence data in the audio data; and removing the mute data from the audio data to obtain the effective data.

In this embodiment, when the network quality of the data receiving end does not satisfy the data transmission condition, the communication data to be sent to the data receiving end can be cached to obtain cached data; when the network quality of the data receiving end meets the data transmission condition, the received real-time communication data can be sent to the data receiving end by adopting a first transmission channel, and a prompt message for checking the lost data can be sent to the data receiving end; and when the data receiving end requests to check the lost data, the second transmission channel is adopted to send the cache data to the data receiving end. In the implementation mode, on the premise of fully considering the subjective intention of the user, two different transmission channels are adopted to transmit the real-time communication data and the buffer data, so that the risk of communication data loss caused by unstable network environment is effectively reduced.
